At 1850 square feet, the Prairie Passive is an extremely energy efficient two bedroom, two bathroom home. Designed for aging in place and accessibility, the unique floor plan optimizes views of the harbor despite the narrow lot. Carefully placed windows and a screened outdoor entertaining area with gas fireplace, provide privacy and a place of refuge in the bustling public marina setting. True to the prairie style, the form was kept low and friendly with hipped roofs and broad overhanging eaves. This ultra energy efficient home relies on extremely high levels of insulation, air-tight detailing and construction, and the implementation of high performance, custom made European windows and doors by Zola Windows ( http://www.zolawindows.com/) . Zola’s Thermo Wood line, which boasts R-11 triple glazing and is thermally broken with a layer of patented German Purenit®, was selected for the project. Natural daylight enters both from the Zola tilt & turn and fixed windows in the living and dining areas, and through the terrace door that leads seamlessly outside to the natural landscape.
